In' this fvi ew,,there is also'parltlyshown the external part of body portion. 3,. likewise the v.baseportion 1. I

" *The' int'ake piece 1 consists. of an air collectingfunnell 16 adapted to be turned toward the. moving air current to ,1 direct the fresh. air}, into. the apartments to be ventilated, and a lower cylinder part, er. section 17 surrounding the upper part of the body .portion 3. A transverse partition 18 divides the intakepiece at about the plane of the junction of the portions 16 and 17 forming two separated chambers. ,In, orderthat-the intakepiece maybe supported so as to be -freely revolved 'it isprovided with an upper cylindrical bearing. 20. above. the partition ;.18' and a lower cylindrical bearing 21, the latter being at the lower end of the-intake I piece and below an inwardly .flaringsection 19-thereof To this latterbearing issecured the gear ring 2 constituting partofthe turningmechanism forthe intake piece. .The

upper bearing. 20 which is preferably formed by a flange extending upwardly from the transverse partition 18 is closed by a, cover a piece 22 that is perforated to permit the free passage of the, fresh air taken in through the air collecting funnel 16. The

partition 18 and cover piece 22 with the cylindrical part that constitutes the bearing 20 may together be considered as the transverse partition dividing the intake piece.

A hood 5 is supported above the cover piece 22' and protects the openings therein from rain or other form of condensed moisture that may enter the funnel. Any water that collectsupon and is shed by the hood flows into an annular channel formed betweenthe bearing 20 and the adjacent wall of the funnel 16, where it collects upon the partition 18 and whence it is carried ofi through drain pipes 6' that deliver into the open, these extending preferably from the partition 18 to the flaring section 19 of the intake piece, in which parts they have bear ing so as to be firmly supported. In the lower'part of the intake piece are formed a number of openings 7 that serve. as theoutlets for the spent air,- these being preferably located; all around the intake piece, in the .fiaring section 19, and, if desired, in the lower part of the cylindrical section 17 of the intake piece, as clearly shown in Figs. l, 2 and 6.

-As already stated the gear ring 2 is atqtachedito intake piece 1, and is operated a pinion 8, mounted on a spindle 9, support,-

] ed'by-suitable brackets 14,'mounted on body portion 3; the spindle 9 with pin1on'8 being operated by a lever 10, and thusby thismeans, the relative position of intake piece 1 to that of body portion 3 may be l [The body portion 3 of the apparatus is v 10" formed, with a lower-portion 24, preferably cylindrical in shape, and adapted to have telescopic connection with the base por- I 'tion4, that is fixed to'the structure to which the "ventilating apparatus is applied, as by means of its securingfiange 11. f The body portion 3 is also formedw'vith an upper cylindrical portion 25Itl1at registers telescopiacally with and serves as asupport for the f bearing of the intake piece l. Likewise the lower bearing 21 of the intake piece 'engages with and is supported by the upper ipart' of the lower portion 24 of the body portion 3. In an'apparatus constructed as 7' represented in the drawings the lower cylindrical portion 24 is approximately half "Ithelength 'of the entire body piece 3, and

extendsv from the 'supporting'flange 11 of "the base piece-'4 to a little abovethe upper edge of the bearing 21 of the intake piece.

1 It 'isdivided' by'a transverse partition 23 to'form two ducts or passages,one; 15,'for the fresh air, and the other, 12, for-the 26, so as to join the cylindrical pa'rty25'iat its" edge or periphery. This arrangement spent air. The partition 23 continuesabove the cylindrical portion 24, forming with the opposing wall 27 a half cylindrical duct that is a continuation of the duct 15, and is, in'its upper part, curved, asindicated at provides a closedfresh air duct 15 leading from the openings through the cover 22 below the hood 5 to the lower end of the body piece 3; and a spent air duct 12 separated from' the fresh air duct by the partition 23 and leading from the'lower end'of the body piece?) to the upper end of the cylindrical portion 24 thereof where the -duct12-opens into the chamber within the intake piece formed'by the cylindrical part thereof below the transverse partition 18.

-From this chamber the'spent air may freely escape through the opening 7; It will thus be seen that while'the body piece 30f the apparatus is stationary and the intake piece freely revoluble relative thereto, the two passages or ducts, one for the fresh air and the other for the spent air, are quite distin'ct one from the othe r,and that the fresh "air is delivered toone and'th'e spent air escapes from the other withequal facility in w'vhichever direction-the funnel of the intake may be turned;

1 a It will be seen by reference to Figs. 2and 6 that the base piece4 is divided bya transverse partition 27 that is adaptedto register miliar' with theart of apparatus.

In order to register, as well as to prevent any relative of. the apparatus may be firmly supported the cylindrical portion 24 of'the body piece so that'thelower edge of the former rests 3 extends beyond the end of the partition i p .01 upon the flangell of-the basepiece," while j; r the lower edge of the partition 23 meets the 1 upper-edge of the partition27,thetfo rmer resting in the s1ots29; p v p ,13 is an attachment below the'base piece 12, 15, for the spent air and the freshair,

Having thus described my invention, what I I claim "and desire to secure by Letters'Patv entis:

1. In a ventilating apparatus, the combi nation of a stationary cylindrical tubular 1 body, a partition dividing'the-said body into "separate air ducts, one, for'incomingflfresh air and the other for outgoing spent air, an

intermediate portion of the said tubular bodybeing cut away on one side of the partltlon, forming an opening for the spent air duct, and dividing the tubular body into .two cylindrical portions, and the upper part of the said partition being curved and united with the wall of theupper cylindrical portionvof the said tubular body making it a part of the fresh air duct, the said upper cylindrical portion being open to the outside air, and a rotary intake piece supported on the said tubular body, such intake piece being provided with bearings that respectively engage with the upper and the lower cylindrical parts of the aforesaid stationary partition.

2. In a ventilating apparatus, the combination of a stationary body piece having a a lower cylindrical portion and an upper cylindrical portion, these being connected by a parti-cylindrical wall, the lower cylindrical portion being divided into a fresh air and a spent air passage by a partition, which partition is extended beyond the end of the lower cylindrical portion and joins the upper cylindrical portion, and, together with the said connecting wall, continues the fresh air passage to the upper cylindrical part of the body piece, an intake piece having a fresh air collecting funnel communicating with the upper cylindrical part of the stationary body piece, and a cylindrical part surrounding the body piece between its cylindrical portions and forming a chamber with which communicates the spent air passage, the said chamber being separated from the funnel by a partition, and having formed in its walls openings whereby it communicates with the open air, bearings carried by the intake piece engaging with the cylindrical portions of Copies of this patent may be obtained for the stationary body piece, permitting the intake piece to revolve on the stationary piece, a hood covering the openings between the funnel and the upper cylindrical portion of the stationary part, and drains for carrying off water that may collect in the said funnel.

3. In a ventilating apparatus, the combination of a base piece of tubular construction divided by a partition into separate air passages, a superposed body piece of tubular construction adapted to fit upon the base piece with a telescopic joint, such body piece being divided by a transverse partition into separated air passages, one for the incoming fresh air and the other for the outgoing spent air, the edges of the said partitions being adapted to come together when the pieces are assembled, and the said parts being constructed to prevent rotative movements of one piece relative to the other after being assembled.

4. In a ventilating apparatus, the combination of a base piece of tubular construction having a partition dividing it into air passages for the fresh and the spent air, a body piece of tubular construction supported upon the base piece, the walls of these two pieces fitting together with a telescopic joint, the body piece being divided into air passages by a transverse partition, the telescoping walls of one of the parts being slotted and the partition carried by the other part being adapted to enter the said slots and to come into close registry with the edge of the partition carried by the other part, whereby the air passages in the,two parts are continuous, and rotative movements of one relative to the other are prevented after they are properly assembled.

In testimony whereof I affix my signature in the presence of two witnesses, this 21st day of February, 1914.
